Just like the title states, I've been attempting to get the giant slayer achievement and was wondering if anyone knows of a good location to find a consistent amount of giants? The only places I'm aware of are parts of events and the information on the wiki is sparse.

Because Risen Giants aren't considered giants for the slayer achievement (at least they weren't on the Giant list), that leaves only the event giants as possibilities, since there are no "roaming" giants. Kol Skullsmasher event in Harathi Hinterlands used to repeat fairly often, but I haven't done that zone since before christmas, so not sure if the event timers have changed.

I've helped defeat Kol Skullsmasher twice as part of large groups (10+). However, the last time I visited the cave where he hangs out, it was a ghost town, and a friend and I proved to be an inadequate match for him.

I once ran into a giant in Brisban in the Toxal Swamp area, and he actually wasn't too hard to defeat solo, but I've never seen him there since.

There is also the champion giant that attacks Nageling regularly, but I'm not sure if he actually counts as a giant. I've helped defeat him several times, but my giant slayer count only shows 3 (which is from Kol x 2 + Toxal Swamp Giant x 1)

I suspect more giants may get added in future updates/expansions. Until then, the Giant Slayer achievement is not really worth the bother.

There seem to be only a handful of giants in the game. Being psychic I can see into the future. Hundreds of people who need this last thing to get their title, camping the spawn spot so when the giant appears, they all attack at once to get one point. Over and over and over again. Hmmmmm. It's possible ANet needs to tweak this just a little.

That's the only giant I've ever killed and my count is at 9 giants, so I'm pretty sure it counts. To get credit for a champion kill in group events, though, you have to do a ton of damage on your own. This is the same issue that popped up during the Lost Shores event, when the monthly asked us for karka kills. You could kill as many vet and champion karkas as you wanted with the zerg, but unless you were specced for direct damage you would never hurt them enough for their kills to count for your monthly.

That might be the issue then. In all the times I've helped face that stupid champion giant in Nageling, I must have never managed to get in enough hits to reach the minimum needed to register the kill. I forgot to mention that this giant has never given me a drop either, so that's probably related to the same issue.

This issue with minimum damage threshold is one of the reasons I really dislike champions in this game. If I spend an entire fight against an enemy, attacking it, putting degen on it, buffing allies fighting it, and helping to rez people that it has put down, I think I should get credit. Alas, it seems that unless you play some kind of glass cannon build that can exceed some overly high minimum damage threshold, all those efforts are for naught. ANet really needs to revisit how they reward players who use teamwork to overcome champions.

Group with other people fighting to reduce the damage you need to do to get credit.

The last one is in the far southwest corner of Brisban. To activate the event you must talk to the broken golem. This one is special!! More Giants will spawn if the event is started off with more players; 2 giants require 2-3 players, 3 giants require 4+. This event upon completion (fail or complete) will respawn every 8 minutes. Since you are able to guest on multiple servers - you can basically do three at a time. Even with that - it took me months to complete this achievement. Good Luck!!
